This class is used to create a volume sphere. Depending on the assigned material, it can be used to render fog or a visible volume of light around a light source. A volume sphere can also be of an ellipsoid shape.

ObjectVolumeSphere Class

Members

static ObjectVolumeSpherePtr create(const Math::vec3 &radius)

Constructor. Creates a new volume sphere object with given radius values.

Notice

If a volume light material is assigned to an object, it is rendered based only on the X-axis radius value. If its radius values along Y or Z axes are smaller, then the object is cut along them.

Arguments

const Math::vec3 &radius - Radius values of the new volume sphere object in units. If a negative value is provided, 0 will be used instead.

Arguments

Return value

Ptr<ObjectVolumeSphere>cast(const Ptr<Node> &node)

Arguments

const Ptr<Node> &node - Pointer to Node.

Return value

Pointer to ObjectVolumeSphere.

voidsetRadius(const Math::vec3 &radius)

Updates volume sphere radius values. If a volume light material is assigned to an object, it is rendered based only on the radius value along the X axis. If its radius values along the Y or Z axes are smaller than along the X axis, the object is cut along them.

Arguments

const Math::vec3 &radius - New radius values of the volume sphere in units. If a negative value is provided, 0 will be used instead.
